To all whom it may concern:

Be itknown tliat we, CARL H. Bissau and CHAnLns B. GARLING, of Syracuse,in the county of Onondaga and State of New York,

have invented a certain new and useful Electrio-Conduit Fitting, ofwhich t e following is a specification. I Y

Our'invention has'for its object the production of a particularly simpleand efficient structure including an electric conduit fit ting, a globe.for an incandescent lamp sup ported by a .socket within the fitting, a

bodying our invention. Fig. 2 is an en larged elevation, partly insection, of parts of said device. Fig. '3 is a section on line 1 A, Fig.1 Fig. 41 is an end view of the for the globe Fig. is a fragmentary viewof the guard,and Fig. 6 1s a pers the eddy of the electric conduitfitting, 1 body having one or more outwardly existing-internallythreaded nipples 2 for connection with conduits, not illustrated, whichinclose electric wires. The body is usually cylindrical in generaloutline and formed with a flat bottom 3 and with an axially projectingcylindrical portion fl: open I at its end and forming an axialcontinuation ,of'the portion of the body provided with the nipples 2.Obviously, the body may be provided with any other suitable meansinstead.

of the nipples.2 for connecting said body to one or more conduits. Thebody is also formed with internal integral posts 5 projecting from thebottom 3 thereof toward the open end of the projecting portion 4,

these posts 5 being spaced apart and de signed to support an electricalappliance, as

a lamp and its socket, the latter being se-" cured to the posts 5 byscrews turning in openings 6 in the ends thereof, and-the pro of saidposts above the bottom 3 pro riding passages for wires between theelectricalfapplianoe and said bot-tom 3. The

" ective view of the locking member for the portion 1 between-the end'face chereof and projecting portion 4 of the, body 1 is provided withan internal threaded surface 7 extending from its outer end andterminating short of the inner end thereof, and is also provided with aninternal annular flange or shoulder 8 located beyond the threadedsurface 7, and with an external annular shoulder 9, usually formed byreducing the outer end of the projecting portion 4.

lO'is an elongated globe having a threaded end which turns in theprojecting portion 4 of the body against a packing ring 11 insertedbetween the end of said globe 10 and the internal annular flange orshoulder 8. By reason of the packing ring, shoulder, and threadedconnection, a vapor-tight joint is formed between the-body 1 and theglobe 10.

A suitable guard forthe globe is provided, the same being here shown ascomprising a supporting member or ring 12 mounted on or encircling theend of the projecting portion 1 of the body, and abutting against theexternal annular shoulder 9, and side members 13 depending from themember or ring 12. Preferably, the member or ring 1.2 is formed withoutwardly extending perforated ears 14: of less thickness than the mainpart of thering, and the ends of the members 13 extend through and areriveted to the ears 14,.Fig. 5. The intermediate portions of the sidemembers 13 are encircled by bands 15. suitably connected. thereto.

The supporting member or. ring 12 is se-. cured to the projectingportion 4 of the body 1 by means of a locking member 16 carried by themember or ring 12 and having an edge portion 17 thereof movable into acir- 'cumferential groove 18 which-is formed in the periphery of thereduced end of said the shoulder 9 and is normally covered by the memberor ring 12. Said locking member '16 is here shown aspivoted at 19 at oneend between outwardly extending ears 20 on the member or ring 12, theedge portion 17 of the pivoted end of the member 16 be ingmovablethrough a hole 21 which is formed in the contiguous'portion of the ringand is normally alined with the groove 18 and projecting into the groove18 when the locking member is in its operative position, and anotheredge portion 22 of saidpivoted end beinglocated opposite to but out ofthe groove 18,when the locking member-is, in its inoperative position.It .isthus. apparent 1 that the edge portions 17 and 22 of the lockingmember 16 are dissimilarly spaced from the axis of the pivot 19 for saidmember 16. Said locking member is formed arc-shape in order to conformto the curvature of the member or ring 12 when said locking member is inits operative position.

Inorder that the guard may not be re-. moved and the globe and electricappliance tampered with by unauthorized persons,

' means is provided for preventing the removal of said guard, and ashere shown, the member or ring l2 and the locking member 16 areprovided, respectively, with perforated-ears 23, 24, the openings orperforations of which are designed to be in alinement when the lockingmember 16 is in its p engaging said projecting portion below theshoulder, substantially as and for the purpose described. 7

2. The combination of an electrical fitting comprising a .hollow bodyfor receiving electric wires, and a cylindrical portion formed with anexternal annular shoulder, the body also having means for supporting anelectrical appliance, a globe supported by said cylindrical portion, aguard'for the globe including a ring encircling the cylindrical portionand coacting with the shoulder and a member pivoted to the ring andengaging the cylindrical portion below said shoulder, giulastantially asand for the purpose speci- 3. The combination of an electrical fittingcomprising a hollow body for receiving electric wires, and a projectingportion formed with a groove in its external face, the body also havingmeans for supporting an electrical appliance, a globe supported by saidprojecting portion, a guard for the globe ineluding a member mounted onthe external face of said projecting portion, and a locking membercarried by the first-mentioned 'member and movable relatively theretointo and out of the groove, substantially as and for the purposedescribed. 4. The combination of an electrical fitting comprising ahollow body for receiving electric wires, and a projecting portionformedwith a groove in its external face, the body also having meansforsupporting an electrical appliance, a globe supportedby said projectingportion, a guard for the globe including a member mounted on theexternal face of said projecting portion, and

.a locking member having one end pivoted to the firstmentioned memberand provided with edge portions dissimilarly spaced from the axis of thepivot of said end, one of said edge portions projecting into the groovewhen the locking member is in its operative position and the other ofsaid edge portions being opposed to said groove and located out of thesame when the locking member is in its inoperative-position,substantially as and for the purpose specified.

5. The combination of an electrical fitting comprising a hollow body forreceiving electric wires, and a formed with a peripheral groove, thebody also havin means for supporting an electrical appliance within thecylindrical portion, a globe supported by the cylindrical portion, aguard for the globe including a ring encircling the cylindrical ortion,and
